[Nix-dev] Re: Handle runtime dependencies

[Wouter db]

This must be a disadvantage of makeWrapper then (i havent looked at it).

But at beforehand delaring what dependencies should be excluded from the 
hash calculation is i think unwanted and error prone (i would say 
impure), you never really know if the build process uses them or not.
